PROBLEM: Most remote controls use IR technology to beam your control commands to your TV,Blue ray player, set top boxes and probably your amplifier. Some cable boxes and odd devices may use RF (radio frequency) technology to ensure your commands work – even if you aren’t pointing the remote at the device in question. When we are away from the tv remote and if we want to operate our TV instead of searching for the remote we can do this by our mobile phone. SOLUTION: SMART UNIVERSAL REMOTE We propose a smart universal remote application technology to overcome the above problem. So by this technology, it can match up the intelligence of the devices being operated and assist users with smart inputs. INTRODUCTION: The process of communication between an emitter (the remote) and a receiver (the device) starts when the user presses any button of the remote, this device has an oscillator and a preconfigured chip that allow the signal to adopt a square waveform with a frequency of 39kHz, depending on the button pressed, the chip will use a determined signal code. This signal travels through the circuit until it reaches the infrared LED, which transforms it into a series of pulses of invisible light (~940nm). If any sensor it's in it's range those pulses will be transformed into a quadratic wave that will indicate what to do according to the programming of the device. HARDWARE TOOLS The hardware we are going to use is the Arduino and the LCD keypad shield, which will help to visualize the menu that will order the codes by their function and the remote they come from . Notice that this shields usually come without the pin headers, without them we won't be able to use the pins that remain free. If your shield don't has them just go to your local electronics store and buy a female pin header, cut it and sand the edges with sandpaper, then just solder them into place. GATHERING CODES: To set up the circuit, we can follow the sketch in the pictures, connecting the signal pin of the sensor to the pin 2 and the other pins to 5V and ground. once the code has been uploaded and the sensor connected we go to "Tools" and we click on "Serial Monitor". You will see a message that says "Ready to decode IR!", now, by pressing any key of the remote while facing the sensor, we will be able to obtain the code TESTING: Once we have finished with the code, the code able to work, make sure you place the infrared LED from digital pin 3 to ground, pin 3 is a PWM pin, other pins won't work. Left and right buttons control the menus, up and down control the submenus, select sends the code attached to the corresponding submenu inside the menu
